摘要
Methods, systems, and computer program products are provided that automatically scale an application between private and public cloud computing platforms, while simultaneous enforcing policies ensuring private data is persistently stored on the private cloud computing platform, but not the public cloud computing platform. A traffic manager on the public platform routes traffic to instances of a web app executing on a private platform. A traffic monitor on the private platform monitors performance criteria of the private platform, and reports traffic telemetry to the traffic manager. Based on the traffic telemetry, the traffic manager may instantiate one or more instances of the web app on the public platform to handle traffic. Private data gathered by such instantiated instance(s) is persisted to storage in the private platform, but not in the public platform.

This is a continuation of U.S. patent application Ser. No. 16/104,055, entitled “AUTOMATIC APPLICATION SCALING BETWEEN PRIVATE AND PUBLIC CLOUD PLATFORMS” and filed on Aug. 16, 2018, the entire contents of which are incorporated herein by reference for all purposes.
Cloud service providers typically offer many types of cloud services including the hosting of web applications, data storage, virtualization, and hosting of essentially any information technology solution. Cloud-based hosting platforms typically consist of inter-networked computer systems or servers, each of which may comprise a number of virtual machines. Cloud-based services are particularly attractive to companies that have seasonal or otherwise variable compute needs because the number of servers, virtual machines or storage and other resources may be scaled up or down to handle the variable load. Such scaling may be performed either manually, or logic may be applied to determine whether compute instances should be spun up or shut down.

What is claimed is:1. A system, comprising:a non-public-network-accessible server set to execute a first instance of an application, the non-public-network-accessible server set comprising:a traffic monitor to monitor at least one performance criterion associated with execution of the first instance of the application by the non-public-network-accessible server set and generate traffic telemetry based on the at least one performance criterion; and a public-network-accessible server set to receive requests associated with the application from computing devices over a public communication channel, the public-network-accessible server set comprising: a traffic manager configured to:receive traffic telemetry and a request; based on demand indicated by the traffic telemetry, route the request to the first instance of the application on the non-public-network-accessible server; and based on demand indicated by the traffic telemetry, instantiate a second instance of the application at the public-network-accessible server set, wherein the traffic manager is configured to automatically scale a number of instances of the application at the public-network-accessible server set based at least in part on the traffic telemetry. 2. The system of claim 1 , further comprising a secure communication channel interface to communicatively couple the public-network-accessible server set to the non-public-network-accessible server set and provide secure transfer of data therebetween. 3. The system of claim 1 , wherein the traffic telemetry comprises at least one of latency, bandwidth, or central processing unit (CPU) utilization. 4. The system of claim 1 , wherein the public-network-accessible server set, and all instances of the application instantiated at the public-network-accessible server set, are configured to not save data received from the non-public-network-accessible server set to persistent storage of the public-network-accessible server set. 5. The system of claim 1 , wherein the first and second instances of the application belong to a same virtual network address space. 6. The system of claim 5 , further comprising a storage of the non-public-network-accessible server set, the storage belonging to the same virtual network address space and communicatively coupled to the first and second instances of the application. 7. A method, comprising:receiving traffic telemetry generating based on at least one monitored performance criterion associated with execution of a first instance of an application by a non-public-network-accessible server set; receiving requests associated with the application from computing devices over a public communication channel; and receiving traffic telemetry and a request via a traffic manager, wherein the traffic manager is configured to:based on demand indicated by the traffic telemetry, route the request to the first instance of the application on the non-public-network-accessible server; and based on demand indicated by the traffic telemetry, instantiate a second instance of the application at the public-network-accessible server set, wherein the traffic manager is configured to automatically scale a number of instances of the application at the public-network-accessible server set based at least in part on the traffic telemetry. 8. The method of claim 7 , further comprising communicatively coupling the public-network accessible server set to the non-public-network-accessible server set and providing secure transfer of data therebetween. 9. The method of claim 7 , wherein the traffic telemetry comprises at least one of latency, bandwidth, or central processing unit (CPU) utilization. 10. The method of claim 7 , wherein the public-network-accessible server set, and all instances of the application instantiated at the public-network-accessible server set, are configured to not save data received from the non-public-network-accessible server set to persistent storage of the public-network-accessible server set. 11. The method of claim 7 , wherein the first and second instances of the application belong to a same virtual network address space. 12. The method of claim 11 , wherein a storage of the non-public-network-accessible server set belongs to the same virtual network address space and is communicatively coupled to the first and second instances of the application. 13. A computer program product comprising a computer-readable memory device having computer program logic recorded thereon that when executed by at least one processor of a computing device causes the at least one processor to perform operations, the operations comprising:receiving traffic telemetry generating based on at least one monitored performance criterion associated with execution of a first instance of an application by a non-public-network-accessible server set; receiving requests associated with the application from computing devices over a public communication channel; and receiving traffic telemetry and a request via a traffic manager, wherein the traffic manager is configured to:based on demand indicated by the traffic telemetry, route the request to the first instance of the application on the non-public-network-accessible server; and based on demand indicated by the traffic telemetry, instantiate a second instance of the application at the public-network-accessible server set, wherein the traffic manager is configured to automatically scale a number of instances of the application at the public-network-accessible server set based at least in part on the traffic telemetry. 14. The computer program product of claim 13 , the operations further comprising communicatively coupling the public-network accessible server set to the non-public-network-accessible server set and providing secure transfer of data therebetween. 15. The computer program product of claim 13 , wherein the traffic telemetry comprises at least one of latency, bandwidth, or central processing unit (CPU) utilization. 16. The computer program product of claim 13 , wherein the public-network-accessible server set, and all instances of the application instantiated at the public-network-accessible server set, are configured to not save data received from the non-public-network-accessible server set to persistent storage of the public-network-accessible server set. 17. The computer program product of claim 16 , wherein the first and second instances of the application belong to a same virtual network address space.
